BTW, my 69 Dart GTS had DART SWINGER stripe on one side and GT SPORT stripe on the other. I am the 2nd owner and bought it in 1978. The original owner's buddy (who was given the car for a debt owed) told him that was the way he bought it. It has a Friday SPD, so could have been started on a Friday and finished the next Monday, who knows? Another never say never, but I didn't care when I restored it, there are GT SPORT stripes on both sides.
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
